TUBE FRAME.

Application inea May ze., 1924. serial No. 715,536.

This invention relates to tube frames for tutt weaving of the general type shown and described in Letters Patent of the United StatesNo. 1,487,442, granted to me March 18, 1924, and is intended to improve that type of tube 'trame by providing a strong and durable construction that will make separable suspension means and spool-bearing brackets applicable to tube 'frames in which is employed a wooden carrier-bar instead oi' a tubular carrier-bar.

lilith these and other objects in view, the invention comprises, generally speaking, a carrier bar, preferably of wood,rprovided at its end with a protective and connecting ferrule overlapping the end portion of the carrier-bar :for a substantial distance to aord, a strong and rigid construction, while still making it possible to carry the row of tutt tubes out nearly to the ends of the bar.

This and other features of the invention will be described in the 'following specification and will be defined in the claims hereto annexed.

In the accompanying drawings I have illustrated a preferred construction and arrangement embodying the principles of they present improvement in which:

Figure l is a rear elevation of an end portion of the carrier-.bar and its suspension means and spool-bearing bracket.

Figure 2 is an end ,elevation of the opposite end of the bar.

Figure 3 is a front perspective of the end portion of the carrier-bar with the spoolbearing bracket and the suspension hanger separated therefrom to show details of the parts.

Figure 4 is a vertical crosssection showing the relation of the carrier-bar to the surrounding errule and the attaching wings by which the spool-bracket and the suspension hanger, respectively, are held in place.

The spool-bearing bracket in its general arrangement and construction is similar to that shown in my former patent and so likewise is the suspension hanger. Y*

In this case the carrier bar l, is presumably made of wood with its top and bottom faces rabbetted or cut away as shown at lb, le, for thereceptionofthe angular attaching feet of the spool-bearing bracket and of the suspension hanger, respectively. At the extreme end the front and rear vfaces of the wooden carrier-bar are cut away for a shorter distance to form a short tenon 1d, to make room for the interposed side wings or attaching members of the spool bearing- ,bracket and of the hanger, respectively.

A. strong metal ferrule 2, receives the cut away end portionof the bar which it overlaps or a'substantial distance to give the requisite area o support and the reenforce-w ment `for the bar. In order to make provision for carrying the row of tutt tubeso that are usually soldered or otherwise secured to a longitudinal attaching strip, close to the end of the carrier-bar structure, the frontv wall 2a of the hollow errule extends inward only a short distance, leaving the remainder of the front open to the inner end of the errule. This allows the tut-tube carrying strip to be secured'to the wooden bar a substantial distance beyond the inside end of the `errule, thereby Y utilizing practically the entire `length of the bar for the` tutt tubes.

The spool-bearing bracket 3, has at its `'upper end an open bearing 3a, ,to form a support `or the spool journal. This upright portion is inwardly offset, and across the ol'set portion is secured a spring metal keeper 4, rivetedl or otherwise secured at 4a against the inside face of the spool bracket, thence extending upward over the outside face of the spool bracket, its middle portion being cut away to permit its application to the bearing bracketv in the manner shown in Figure l. At the left of the upper portionv of the bearing recess 3a, the spring keeper 4 is formed with an angular inset struckup tongue 4b which normally overhangs the yarn-spool journal but can be pressed outwardly to allow the journal to be lifted out of the open bearing.

The attaching means for securing the spool-bearing bracket in position on the carrier-bar comprises parallel side wings 3", and a horizontaltop wing Sdpwhich, after the 'ferrule Vis placed on the end of the carrier-bar, can be inserted between the sides and top of the carrier-bar and the corresponding walls of the ferrule. The top attaching wing 3d is provided with a longitudinal slot or notch 3e to permit an attach` ing screw 30 to be passed through the top wall of the Jerrule andV into the solid end portion of the wooden bar without interfering with the removalV of tbe spool-bearing bracket when desired. betopwall of the ferrulej. also provided nea-1; its end? with another hole 2O `for allowing a short machine screw to be insertedin threaded engagement with. the topwing 39'.

rl"he suspension means, in this case, comprises the upright hanger 5 Whose lowerportion is inwardly turned to forma bottom attaching wing or foot member 5, and in rthe angle between the uprightportionty and the foot member 5C are secured@ Parallel at: taching wings 5b, 'providfedf` with! threaded beles 5@ for.. theA reception of fastening. screws which. are4 passed through aligned holes. in
